Video editing and conversion

Introduction[edit | edit source]

Let's first present a few definitions, taken from various Wikipedia articles.

“Video editing is the process of re-arranging or modifying segments of video to form another piece of video. The goals of video editing are the same as in film editing - the removal of unwanted footage, the isolation of desired footage, and the arrangement of footage in time to synthesize a new piece of footage.” (Video editing, retrieved 16:46, 2 April 2007 (MEST))

“Video capture is the process of converting an analog video signal—such as that produced by a video camera or DVD player—to digital video. The resulting digital data are computer files referred to as a digital video stream, or more often, simply video stream. This is in contrast with screencasting, in which previously digitized video is captured while displayed on a digital monitor. TV tuner cards have a television tuner with the capabilities to capture broadcast television.” (Video capture, retrieved April 22 2012.)

“Video converters are computer programs that can change the storage format of digital video in a process called transcoding.” Comparison of video converters, retrieved April 22, 2012).

“A screencast is a digital recording of computer screen output, also known as a video screen capture, often containing audio narration. The term screencast compares with the related term screenshot; whereas screenshot is a picture of a computer screen, a screencast is essentially a movie of the changes over time that a user sees on a computer screen, enhanced with audio narration.” (Wikipedia, retrieved April 2012)

Problems Most everything is done with a filter who must be attached to an object. Understanding filters requires reading Icons, ribbons and text do not display well on a 4K screen with big fonts. This is a trial version for home use, but it will export after ignoring the warning Very difficult to install under Debian/Ubuntu.

Registration required.

Less functionality than others (but to nice to have for small quick projects)
Input video formats lots (ffmpeg) lots lots

Medium-end popular systems, often referred to as the "A-Team"

Specialized commercial[edit | edit source]

Encoders, converters/transcoders[edit | edit source]

Free encoders / converters[edit | edit source]

(Note: These should be separated into encoders, converters and multi-purpose tools)

Online converter services
Adware and nagware
Unknown status
  • Adobe Media Encoder (Win). This product comes with Flash and CS5 suites, but it looks like it can be downloaded (not tested).

Overviews
Free software (all sorts of licences)
Commercial
  • Adobe Captivate
  • Camtasia
  • ... others (needs to be completed)

Other software[edit | edit source]

  • FFmpeg (Wikipedia). Popular software project that is used in many other open source and commercial products.
  • Gspot is another nice free tool that displays information about at video file. Unfortunately it is outdated (last upgraded in 2007 as of April 2012), i.e. it can't precisely identify new video formats
